TRACTOR ATTACHMNT FDR MOTOR-VEHCLES.

lle it known that l, Finnois il. Henson, residing at `Los Angeles, inthe county et' Los ngeles and State ot (,lalilornia, have inventedcertain new and-useful improvements in Tractor Attachments for Motor-Vehicles, ot which the following` is a speci- ,lication low inc'`vehicle. My present invention provides an improved means forconnecting` the attaclr ment to the auto vehicle frame whereby the saidattachment may be readily attached to vehicles that have no runningboards and to the said trame of the vehicle in such a manner that thetraction attachment may be readily adjusted for being operativelyconnected with' the general. run ot did'crent makes ot motor vehiclesand located either to the front or to the rear oi' the tractor wheels,as conditions may require.

Another object of my present invention is to provide an attachment formotor vehicles or" the general character stated, of a simple,economically constructed and easily manipulated bracket device forholding the endless belt guide or idler roller and adapted to beextended in three directions to readily adjust the said guide rollerwhereby to set the endless tractor belt in the desired position forengagement with the tractor wheel.

l,Vith further objects in View that will later appear my inventionconsists inthe peculiar, combination and novel arrangement of the partshereinafter fully de- -scribed', specifically pointed out in theappended claims and illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of so much of a motor vehicle as isnecessary'to illustrate the application of my invention;

Fig. 2 is a transverse section thereof taken on the line Q--2 on Fig. 1.

Fig. 3 is atransverse section o'l" the bracket device taken on the line3 8 on Fig. 2,

looking in `the direction ol the arrow a,

'to the Vllrrminj.,r l. oi thc machine.y and thereby provide l'or theoperative connection of the endless tractor belt to the said wheel 2.

loller i323 is journalcd in and is endwise slidable through the bearings3l 3l on the llorkcd members 30m-3() and is held within the bearings Elby the cap plates 32, as shown` 3l designate grease cups for thebearings l.

al designates a channel iron attached to 'the 'frame member l andpendent therefrom and Vthe said iron 'lincludes an apertured outwardlyextended lue' l2, the pu lpose Of which will presently appear.

second bracket member (il). also of Channel iron, is pendently mountedon bracket member l and the said member G0 includes a vertical extension(S that has an elongated slot 7 and is held tor dill'erent verticaladjustments on the said member Ll, by a clamp nut S, and the verticallyadjustable hanger bolt 11 that engages an outwardly projected lip 10 onthe extension G and passes through the apertured member 12 of thebracket 4 to receive the zuljustingc,V nut 13, asis best shown in Fig.2.

The said second bracket member also includes a horizontal extension (S1,on which is supported, 'for `lateral adjustment, with respect to theframe 1, a channel iron bracket 15 having a longitudinal slot 16 toreceive a screw stud 17 having a pendent block 18 and lixedly held onthe extension 61 by the clainp nut 19. v

Bracket 15 is adjusted laterally tothe iframe 1 by a screw bolt 20 Whosehead portion engages the block 18, and Whose threaded end passes throughan apertured ear 22 of the bracket l5 and which receives the adjustingnut 21, as shown.

Bracket lo' has a slot 23 at right angles to the slot 1G through whichpasses an adjusting bolt 24 pendent from the bracket 25 that carries theidler roller 33, and clamps the said bracket to its adjusted positions,to which it-is shifted by a screw bolt Q8 Whose head engages a lug 26 onthe bracket 25 and an apertured member 27 fast on one edge of thebracket 15.

9.9 indicates the adjusting nut or bolt 28. From the foregoingdescription, taken in connection With the drawing, the completeconstruction of my present invention will be. readily apparent.

By reason of providing a bracket device, as shown and described, asimple effective and easily manipulated means is provided foroperatively positioning the idler or guide roller with respect to thetraction wheel to which it is intended to apply the endless tractorbelts, since in my said construction of bracket the bearings for thesaid idler roller can be adjusted vertically, laterally andlongitudinally (backwardly and forwardly) 'with respect to the sideframe of the motor vehicle.

The endless belt, in practice, of rubber, or other suitable material,when not required for use, can be carried in the tool box and after thebelt has been used, it can be quickly removed, by loosening one of thecap plates to free the end of the roller 33 which can then be easilyslid endwise out of the bearings 2li-31 and from engagement with thebelt. After the belt is removed, the roller 33, is shoved back and heldin place by closing over the cap plate.

By reason ot'providinga bracket device for sustaii'iing the guide roller33, my improved tractor attachment can be readily so applied that thesaid roller 33 may be positioned either to the front or to the rear ofthe tractor Wheel.

That I claim is:

l. ln a motor vehicle, the combination with the Wheel and an adjacentportion of the vehicle, of a bracket device supported 0n said portion oithe vehicle and extensible longitudinally with respect to the vehicleand Wheel, an idler roller mounted on the said device in a planeparallel with the Wheel axis, and an endless belt that takes around theroller and the Wheel.

2. In amotor vehicle, the combination with the wheel and the adjacenttrame portion ot the vehicle; of a bracket device supported Jon theframe and including members extensible laterally, longitudinally, andvertically ivith respect to the frame and the ivheel, an idler rollermounted on the said device in a plane parallel with the Wheel axis andan endless belt that takes around the roller and the Wheel.

3. ln a motor vehicle, the combination with the Jframe, the tractorWheel; of a guide roller cooperative with the Wheel, an endless beltthat takes over the Wheel and the guide roller, meansor supporting thesaid roller in alinement with the tractor Wheel, said means beingadjustable vertically, laterallv and longitudinally with respect to theWheel and the frame, the said means including a bracket member securedto and vertically adjustable on the frame, a second bracket membersecured to and laterally adjustable relatively to the frame, and a thirdbracket member secured to the second bracket member and longitudinallyadjustable with respect to the said frame, said third bracket memberhaving bearings for the guide roller.

4. In a motor vehicle, the combination with the frame, the tractorWheel; of a guide roller cooperative with the wheel, an endless beltthat takes over the Wheel vand the guide roller, means for supportingthe said roller in alinement with the tractor Wheel,

said means being adjustable vertically, lat-A erally and longitudinallywith respect to the wheel and the frame, the said means inchidmg abracket member secured to and vertically adjustable relatively to theframe, a second bracket member secured to and laterally adjustablerelatively to the frame, a third bracket member secured to the secondbracket member and longitudinally adjustable with respect to the saidframe, said third bracket member having bearings for the guide roller,said guide roller being end- \vise removable from the said bearings andmeans for holding the said guide roller from endwise movement in thebearings.

5. A traction belt guide attachment for motor vehicles comprising adevice adapted to be engaged by the belt, and a sectional bracket memberfor carrying said device, said bracket member being carried by thevehicle and having provision whereby said device may be rearwardly,longitudinally and vertically moved for adjustment as to position withrelation tothe vehicle Wheel.
